Изобретение относитс к области Термоиэмерений.The invention relates to the field of Thermal Measurement.
Известны составы дл изготовлени термонндикаторных карандашей, содержащие термоиндикаторное вещество, пигмент, наполнитель и св зующее ij и 2.Formulations for the manufacture of thermo indicator sticks are known, which contain a heat indicator substance, a pigment, a filler, and a binder ij and 2.
Наиболее близким по технической сущности вл етс термокарандаш плавлени , содержащий термочувствительное вещество, наполнитель, пигмент,св зующее и растворитель з.The closest in technical essence is a thermopencil melting, containing a heat-sensitive substance, a filler, a pigment, a binder and a solvent.
Недостатками указанных составов вл етс нестабильность показаний, т.е. температура перехода цвета действнтельиа в услови х подъема температуры в течение 2 мин и выдержки при достижении температуры перехода в течение 15-30 сек.The disadvantages of these compositions are the instability of the indications, i.e. the transition temperature of the color is actual under conditions of a rise in temperature for 2 minutes and holding at a transition temperature for 15-30 seconds.
При этих услови х точность измерени составл ет . Кроме того, ввиду плохой адгезии (4 балла)термокарандашна метка указан-ного состава наноситс только на нагретую поверхность металла. Недостатком зтих термокарандащей вл етс также неконтрастность цветного перехода - до воздействи температуры черный сплошной рлед, после воздействи температур серый несплошной след. Эти недостачUnder these conditions, the measurement accuracy is. In addition, due to poor adhesion (4 points), the thermal pencil tag of the indicated composition is applied only to the heated metal surface. The disadvantage of these thermocouples is also the lack of contrast of the color transition — a black solid trace before the temperature, and a gray non-continuous trace after the temperatures. These shortages
